Today Microsoft launched Tafiti, a new demo/experiment showing in a cool way what you can do combining Live Search with Silverlight. I hear you thinking: not another search, or Microsoft, huh!, … but I think you should take a look at it.
Tafiti, which means ‘do research’ in Swahili apparently, allows you to search the web like any other engine when it comes to the results themselves. But the way these results get presented and the way you can drag into ‘shelves’ where you can collect them is quite interesting.
I did a search on ‘silverlight’ and the view on top is where you see the news results of it, nicely presented in ‘newspaper’ style. In the carrousel on the left you can choose other verticals (web, images, …) and on the right you have the ‘shelves’ I mentioned earlier with some results stored on the first ‘shelve’. You can actually open up the results on a ‘shelve’ which shows all of them in one view and which has a blog it & email it buttons so you can send them through right away.
I’m going to play around with this a bit more myself, but make sure you do as well. I think it’s an interesting exercise. You can see a video of Tafiti in action at On10.

Those interested in another search mashup and visualization tool may want to visit searchCrystal, which lets you search and visually compare multiple engines in one place. You can remix and share results from web, image, video, blog, tagging, news engines as well as Flickr images or RSS feeds.
